I hope it won't be necessary, but if force is necessary to prevent Iran from acquiring nukes, it won't be a land war. It will be only to destroy Iran's nuclear weapons program and to prevent it from exporting war to the rest of the ME.
I hope the same thing, and i agree that will strategy will be that we hope for. But, if they go underground, ots not so simple.
What if it is determined that they have an underground facility and will likely have ten bombs in a year? That's not happening any time soon, but it's a contingency that has to be considered.
The iranian government is oppressive. But they have total control of iran. It's not like libya, where qhaddafi had little to no sovereignty over most of the country.
